Can someone who is filling out the form, save it if they can't complete it in one sitting?

"Can someone who is filling out the form, save it if they can't complete it in one sitting?"  

I have created a survey in Jot.form, which I sent to clients to complete. One client asked me the above question. Please let me know if that is possible, and how to instruct them to do so.

Thanks.  

Hi,

Yes it is possible, Enabling the AUTOFILL feature will automatically save the form's field values locally (browser local storage) for up to 24 hours.
